PHOTOGRAPHIC-FILM HANGER.

To all whom it may concern Be it known that I, GUY C. Cnoss, a citizen of the United States, residing at Denver, in the county of Denver and State of 0010- rado, have invented new and useful Improvements in Photographic l ilm Hangers, of which the following is a specification.

The present invention is directed to improvements in photographic film hangers, and ')articularly to those employed for hanging'cutfilms in the usual tank baths during developing, fixing, andwashing, and during the drying process.

The invention has for its object to provide a hanger of such construction that it may be used in a perpendicular position during the entire successive operations ofdeveloping, fixing, washing and dryin Another object of the invention 15 to provide a hanger of this character so constructed that the films when engaged therewithwill hang in such positions as to positively prevent the same from touching each other, or coming in contact with the hanger, thereby eliminating any possibilityof the films becoming scratched or marred in any way whatsoever. v

A further object of the invention is to provide a hanger of this nature having associatedtherewith novel means forattaching the cut films to the hanger.

A still further object of the invention is V to produce a hanger so constructed that the film negatives will be held in proper spaced relation during the developing, fixing and washing in the deep tank method of development, thus assuring free access of the respective solutions to the backs and faces of the films, and to ban free when drying.

With these an other objects in view, this invention resides in the novel features of construction, formation, combination and Patented Nov. 23, 1920.

the spurs in penetrating engagement with the film negative. i

Fig. 5 is atragmentary perspective view oi the hanger.

The hangerc omprises abody 1, which is formed from a single length of suitable sheet metal, said body being corrugated transversely, whereby the apeXes 2 of the corrugations will be disposed in vertical staggered relation, asclearly shown in Fig. 2 of the drawing, the purpose of which will later appear. I

The body 1 is of such length that twelve film negatives may be conveniently attached thereto for the different treatments which they are subjected to. 1 r

The upper end of the body 1. terminates in a hook 3 which is adapted to detachably engage the usual rack, whereby the hanger, with its capacity of films, can be suspended within the usual tank baths during developing, fixing and-washing.

The apexes 2, as well as thelower terminal i, are provided'with-upper and lower paired perforations 5 and G, respectively, the former being slightly greater in diameter than the latter.

On opposite sidesot' the body 1 are secured,.preferably by rivets 7, the upper ends of the resilient sheet metalarmsS, the lower ends of which terminate in "furcations 9, which in turn terminate in angular ifingers 10. The fingers 10 have associated therewith spurs 11, said spurs being adapted to enter the perforations 12 and '13 formed in the arms, said perforations being in registry with the perforations and 6, respectively. It will be noted that parts of the angular fingers 10 slide in the perforations 5 and 12 of the' respective arms and body, while the spurs 11 enter the registered perforations 6 and 13, as clearly shown in Fig. 4 of the drawing.

The hanger is designed especially for use in connection with cut films, or those films which are sold in packs. In Figs. 2 and 4 film negatives 14L are shown attached to the hanger, and it will be observed upon reference to Fig. 4 that the spurs 11 penetrate the negative and hold the same firmly connected with the hanger.

Since the arms 8 are resilient it is obvious that the same can be readily flexed toward the body 1, whereupon the spurs disengage the perforations 6 and 13, thus leaving a passageway for the film M to be inserted. Upon releasing the arms 8 the spurs 11 will enter the respective perforations, and in so doing will penetrate the film, thus securely attaching the same to the hanger, and as clearly shown in Fig. 4.

From the foregoing it will be apparent that the film negatives 14; will be suspended the hanger in such a manner that the same will not contact with each other, or with the body of the hanger, since the apexes 2 are disposed in staggered relation.

It will be observed that the relative arrangement oi": the fingers 8 and body 1 is such that the same will. reinforce the hanger at the corrugated portions.

That is claimed is:

l. A film hanger comprising a body, said body being corrugated transversely, the apexes oi" the corrugations having means associated therewitlrto attach the films to the hanger.

A film hanger comprising a transversely corrugated body, the apexes of the corrugations being disposed in staggered relation, and means for retaining films on the apeXes of the corrugations.

A film hanger comprising a transversely corrugated body, the apexes of the corrugations being disposed in staggered relotion, as and for the purpose set forth.

i. A. film hanger comprising a sheet metal body, said body having transverse corrugations formed therein, the apexes of the corrugations being disposed on opposite sides of the body, resilient arms having one of their ends fixed to the body, and their other ends provided with spurs for penetrating the films and entering the body to hold the films engaged with the hanger.

- 5. A film hanger comprising a body having transverse corrugations formed therein.

means for suspending the body in a pcrpendicular position, and means on opposite 5. a of the body to attach films thereto.

8. A film hanger comprising a trans-- versely corrugated body, the upper end of which terminates ina hook adapted to do tachably engage a support to suspend the body in a perpendicular position, and Illtillls associated with the apexes of the corrugations to attach films thereto.

9. A film hanger comprising a body having transverse corrugations formed therein. spring fingers being for a portion of their length riveted to the body flush with the corrugations, and means associated with the fingers for retaining films on opposite sides of the body.

10. A film hanger comprising a body, said body having perforations formed therein. resilient arms fixed on opposite sides of the body, and having spurs associated therewith for movement into and out of engagement with the perforations, and a hook carried by the upper end of the body for de taehably engaging a support, as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
